Carry out the roofing of metal roofs with your own hands - the task is rather difficult if you do not have any building experience. However, experts say that when studying detailed instructions and the presence of sensible helpers, especially if the roof that needs to be covered with a conventional shape, then nothing is impossible.

The main advantages of metal tile

Along with the widest range of roofing materials, metal tiles are in great demand today. This is due to the whole range of its advantages:

  • excellent resistance to different temperatures, as well as to its differences;
  • longevity of use - the bright colors of the metal tile virtually do not burn out in the sun over the years, and your house will be as new and after many years;
  • strength - an undeniable quality of metal. The production is being perfected over 30 years of its existence on the market, today it is the most complicated process of covering profiled sheet of galvanized steel with specially developed polymers and varnish;
  • the cost of covering the roof with metal tiles is quite loyal, which also speaks in favor of choosing this particular material;
  • roofs, covered with metal sculpture, look aesthetically pleasing, rich and beautiful.

Delivery and storage of material

Having selected profiled sheets in the store, several questions may arise with their delivery to the construction site. Here are some important tips that need to be considered:

  • direct loading and unloading of material should be carried out exclusively by a mechanized method. Only in this case the manufacturer retains its warranty obligations;
  • if you get a lot of material and do not plan to install it for quite some time, then the sheets must be unpacked and stacked on each other, be sure to separate the
  • wooden slats so that the workers carry the sheets, keeping them at the top along the sheet. The transfer of sheets should be carried out at the rate of 1 person per 1.5 running meters of material. In no case should you allow sheets to sag during transport.

Roofing technology

The technology of roofing with metal roofs implies several rather complicated stages:

  • roof cake installation;
  • pruning and preparation of profiled sheets for installation;
  • laying and fixing screws metal to the crate.

Installation of roof pie

It is important to consider that the technology of roofing with metal roofing, first of all, requires the preparation of the roof pie. A cake is called a construction of several layers, each of which has its own purpose. The design of the pie differs depending on whether it is planned to build a warm or cold roof.

Cold roofing is most often chosen for non-residential premises and includes:

  • waterproofing film layer;
  • control the grating;
  • crate;
  • initial crate;
  • rafters.

A warm roof suggests a more complicated construction of a roofing cake, because of which the roofing of the roof with metal tile will already increase its price a little, but the money factor here plays a smaller role, as the roof overhead is done for many years. The roofing pie of the warm roof includes:

  • one-side vapor barrier, which will release moist air, but do not let in;
  • rafter system, which will carry the basic, load-bearing function for the roof. It includes both rafters and longitudinal girders;
  • inside the rafter system layer of heat-insulating materials;
  • among the thermal insulation must definitely leave the ventilation gap;The
  • control unit performs several functions at once: it fixes the waterproofing and is the fastening for the crate;
  • crate, on which the sheet of metal tile is later fastened. The material for the crate can be treated with special antiseptic wooden bars, as well as a perforated profile of galvanized steel. The crate is fastened with a certain step, which usually does not exceed 45 cm;

Cutting and mounting of metal sheets

Cutting sheets of metal tile - the initial stage of its installation. Almost always it has to be performed on the ground, after which it is already raised to the roof. In general, experts recommend that you use it as rarely as possible to cut it, but if you still need it, you should always remember a few rules:

  • personal protective equipment in the form of glasses and gloves should always be with you, do not neglect them;
  • cutting of metal sheets suggests that there is no use of any abrasive tools, this will damage the protective layer of the coating. Use a jigsaw or a saw blade;
  • cut places must also be protected. For this, be sure to purchase a special paint and cover it with an unprotected sheet of paper.

Going directly to the installation, first of all remember that the cut off areas should be attached to the whole - this will preserve the longevity of the coating.

Fixing of metal tiles

Special screws are used for fixing metal tile, the size of which is 4.8x28 mm. Self-tapping screws should be covered with a special protective coating for the color of the metal tile itself. The average consumption of self-tapping screws on the roof is up to 10 pcs.for 1 m2.

  1. For more dense fixing, it is important to use washers to seal the screws.
  2. Before starting fixing, the sheet of metal tiles must be drilled in the places of self-tapping. It is not recommended to screw them on yourself, because it is possible to damage the protective layer with which the sheet is covered.
  3. The important point is that the screw is attached exclusively perpendicular to the crate, any inclination is inadmissible.
  4. Fixing the screws, count the force: it should not be too tightly to attach the metal to the lathing, the roof should be as if slightly pressed. But too weak fixation can not be left.
  5. Additional fixing screws require a place where there are overlaps - this will increase the reliability of the roof.
  6. Beginning the roof, first align the ends with respect to the eaves, after which you just need to start fixing.

Depending on the shape of the roofing roof, there are several basic technologies for starting a roofing with a metal roof:

  • can be started at the roof of a gable roof, from the right or left - it does not matter;
  • if the sheets are placed on the right, then the edge should overlap the previous one, and if left, then under the previous sheet;
  • if the roof is tent-like, then the sheets of metal should be laid from the top to the bottom and, as they are mounted, go sideways.

After completing the installation on the roof slopes, you need to start installing the final elements. The ridge of the roof is decorated with a ridge strip, all skate elements of metal tile should be fixed to it with screws. Butt joints are fastened to all places where the tile leaves are adjacent to the vertical surface.
